A 20.0 mL solution of strontium hydroxide, Sr(OH)2, is placed in a flask and a drop of indicator is added. The solution turns color after 20.86 mL of a standard 0.0500 M HCI solution is added. What was the original concentration of the Sr(OH)2 solution? The unbalanced equation for this titration reaction is HCI + Ba(OH)2 --> BaCl2 + H2O
How many mL of 0.26 M NaOH is need to titrate 26 mL of 0.436 M HCI to the equivalence point?
How many mL of 0.26 M NaOH is need to titrate 20 mL of 0.104 M H3PO4 (Phosphoric Acid) to the last equivalence point? The unbalanced equation for this titration reaction is NaOH + H3PO4 --> Na3PO4 + H₂O
HBr is a strong acid. What would be the pH of 1.14 M HBr solution? Question 5 What would be the pH of 1.854 potassium hydroxide solution? 1 pts
Methylamine, CH3NH2, is a weak base (Kb = 4.6 x 10-4). Estimate the pH of 2.72 M methylamine solution. Question 7 0.5 pts Formic acid, HCHO2, is a weak acid (Ka = 1.8 x 104). Estimate the pH of 0.94 M formic acid solution.
What kind of personal protective equipment (PPE) should be worn when working with high concentration hydrocloric acid (HCI)? For the safety data sheet visit Flinn Scientific SDS for hydrocloric acide. Goggles, gloves, closed toed shoes, and clothing that covers the body. O Only gloves, because you don't haveto worry about splashing or spilling this chemical. Only goggles because you only have to worry about splashing your eyes. Nothing, HCI is safe to work with.
